Wrong. You can have any beam pattern with any type of housing. it's all in the optical design. I have E-Code lights in my 951 and 914. They are reflector housings and have a VERY sharp horizontal cutoff. One could design a projector housing that threw a lot of light upward. It is not an inherent function of projector versus reflector, but rather a function of a country's legislation regarding beam pattern.Originally posted by: Aharami
Beacuse of the cutoff inside the projector, HIDs have less glare than 99% of halogens in reflector housing (which throws a lot more light upward than any projector.) Unless ofcourse the HIDs are aimed improperly and the cutoff is above oncoming traffic's eye level.
The US has continually lagged behind Europe in terms of beam-pattern (as evidenced by the US requirement for sealed beam lights well into the 1980's) and it has only been in the last few years that the US has begun to bring its required headlight beam pattern more into line with European requirements. Coincidentally, this has also been the time at which many European and luxury cars are moving to projector housings as opposed to reflector housings. The change in housing type is unrelated to the beam pattern.
The use of ANY bulb other than the specified type in ANY housing will result in an improper beam pattern. Housings are built to work with the light coming from a specific point and any chance in the origination of the light source has significant impact on the beam pattern. This is why aftermarket HID kits are never a good choice. The only acceptable way to mount HIDs after the fact is to replace the entire housing and lens with an OEM uint.
